GEORGE W. SMITH, OF DALLAS, TEXAS.

GRAPPLE.

To (LZZ whom, it may concern:

Be it known that I, GEORGE W. SMITH, a citizen of the United States,residing at Dallas, in the county of Dallas and State of Texas, haveinvented new and useful Im provements in Grapples, of which thefollowing is a specification.

My invention relates to grapples; and its primary object is to provide anovel and highly-useful device of this character which is designed toengage a building-block in a manner to prevent injury to and itsaccidental disengagement from a block.

A further object of my invention is to provide a grapple which may bereadily and quickly applied and removed from a build ing-block, onewhich is simple and durable, and one which may be manufactured and soldat a comparatively low cost.

With the above and other objects in view the invention consists in theconstruction, combination, and arrangement of parts hereinafter fullydescribed, claimed, and illustrated in the accompanying drawings, where-1n Figure 1 is a perspective View of a grapple constructed in accordancewith my invention, the same being illustrated as applied to abuilding-block; and Fig. 2 is a detail perspective view of one of thecorner-clamps.

Referring to the drawings by referencenumerals, 2 designates angleclamping members which are adapted to be applied to the corners of abuilding-block in the manner illustrated in Fig. 1 of the drawings andby means of which the block is adapted to be hoisted and set in place.Reinforcing-straps 3 are secured to the outer faces of the clamps 2 andhave their ends offset, as at 4, to permit the application ofelbow-levers 5 between the clamps and straps. The elbowlevers 5 arepivotally secured in applied position upon the clamps 2 by bolts 6 andnuts 7. The operating ends of the levers 5 are formed to provide jaws 9,which are adapted to engage connecting members or the links ofchain-sections 10, whereby whenupward pressure is applied to the powerends 11 of Specification of Letters Patent.

Application filed June 16, 1906.

invention, what I claim is Patented Jan. 29, 1907.

Serial No. 322,058.

said levers the clamps 2 are brought into and held firmly in engagementwith the corners of a building-block. The power ends 11 of the levers 5are perforated, as at 12, to permit chains 13 to be attached thereto.The chains 13 are suitably connected to a hoisting mechanism, and whensaid mechanism is operated to hoist a block an upward pressure isexerted upon the power ends of the levers 5, whereupon the corners ofthe clamps are brought into and held firmly in engagement with theblock. I

It should be apparent that in view of the manner in which the grapple isapplied to the block a pressure is always exerted to firmly hold theclamps in engagement with the blocks during the hoisting of the same. Italso should be apparent that the grapple will not in any manner injurethe block and that in View thereof it is admirably adapted for hoistingblocks of polished marble, granite, and the like.

Having fully described and illustrated my 1. A grapple comprising angleclamping members, levers pivotally mounted upon said clamping members,and a connecting member secured to the operating ends of the levers tocause the clamping members to be secured in position when power isapplied to the levers.

2. A grapple comprising angle clamping members, straps secured to saidclamping members and having their ends spaced therefrom, elbow-leverspivotally mounted upon the clamping members between the same and saidspaced ends of the straps, and connecting members secured to theoperating ends of said levers to cause the clamping members to besecured in position when power is applied to the levers.

In testimony whereof I afliX my signature in presence of two witnesses.

GEORGE W. SMITH.
